ATB(偶氮特异丁烷)是一类性能良好的自由基引发剂、用它引发交联OV-1701石英弹性毛细柱,交联度大于96％,柱子内壁惰性,柱效高,热稳定性好,交联前后柱极性无明显变化,文中还对交联条件和反应机理进行了研究和探讨。
ATB (azo-butane-butane) is a kind of free radical initiator with good performance. It is used to initiate cross-linked OV-1701 quartz capillary column with a cross-linking degree of more than 96%. The inner wall of the column is inert, Good, the polarity of the column before and after cross-linking no significant change, the article also on the crosslinking conditions and reaction mechanism were studied and discussed.
